电压暂降是电能质量的主要问题之一，动态电压恢复器DVR（dynamic voltage restorer）是1种有效的解决方案。由于传统DVR无法适应中压领域应用，首先介绍1种基于级联H桥多电平变流器的高压直挂式DVR；为提高系统的响应速度及补偿精度，提出1种用于DVR交流电压补偿控制的dq轴解耦策略，同时采用基于电压补偿分量注入的载波相移脉宽调制策略，解决级联H桥直流侧电容电压平衡问题，保障了系统的安全性和稳定性；最后通过MATLAB/Simulink对所提出的DVR及控制算法进行建模与仿真，验证了该方法的有效性和可行性。

Abstract

收起

Voltage sag is one of the main power quality problems, and dynamic voltage restorers (DVRs) provide an effective solution. Since the traditional DVRs are unsuitable for medium-voltage applications, a high-voltage direct-connect DVR based on a cascaded H-bridge multilevel converter is introduced. To enhance the response speed and compensation accuracy of the system, a dq-axis decoupling strategy for the AC voltage compensation control of DVR is proposed. Meanwhile, a carrier phase shifted pulse width modulation strategy with voltage offset injection is also employed to balance the DC-side capacitor voltage of the cascaded H-bridge, thus ensuring the safety and stability of the system. Finally, the proposed DVR and the corresponding control algorithm are modeled and simulated by MATLAB/Simulink, demonstrating the effectiveness and feasibility of the approach.
